Gluten-Free Bake Mix with gelatin - I am finding the two bake mixes which are similar, but one uses xanthan gum and the other unflavored gelatin are pretty much interchangeable. That's good news!! Sometimes with cookies, the gelatin is not necessary. Gelatin or xanthan gum are just there to prevent crumbly outcomes.
(a concentrate from EZ-Sweetz - sucralose or stevia)
(please note for these cookies, if you are using Bake mix 2 - no need for gelatin)
